Identifying task groups for organizing search results

ABSTRACT

Computer-readable media and computerized methods for automatically organizing search results according to task groups are provided. The methods involve aggregating a gallery of entities (e.g., search queries that share a common categorization) into a query class and assigning a dictionary (e.g., list of terms that are drawn from various sources) to the query class. The task groups are identified from the list of terms within the dictionary. The process of identification includes analyzing patterns of user search behavior to select terms from the list of terms, which reflect popular user search intents, and ranking the selected terms based on predetermined parameters to produce an ordering. Based on the ordering, a set of the selected terms that are highest ranked are declared the task groups. The task groups are employed to arrange the search results on a UI display and to provide a consistent and intuitive format for refining a search.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not applicable.

BACKGROUND

Various techniques exist that enable Internet-based search engines toreceive and process queries from users and to provide search resultsbased thereon. Because these search engines are typically coupled withdata stores, queries, search results, and other search data may beconveniently stored for subsequent access. Analysis of this availablesearch data may be interesting to identify trends within patterns ofInternet use and to arrange search results based on those trends.However, existing methods for retrieving the search data are ineffectivefor detecting trends or implementing an intuitive arrangement of searchresults.

Generally, the existing methods and present techniques are configured tooffer users a standard search experience that involves locating andpresenting in a single list a particular number of search results thatare semantically-related to the query. However, these existing methodsare inappropriate for properly managing the search results on a userinterface (UI) display and for providing a user with an organizedexperience. In particular, present techniques do not offer sufficientevaluation of the search data to group information based on top userintents and tasks associated with a query. Thus, these presenttechniques are inadequate for sorting search results on a UI displaybased on the user's intents and tasks. Accordingly, employing aprocedure to organize search results that are responsive to a query,where the arrangement of the search results is based on a user's intentsand tasks deduced from the query, would enhance a user's experiencesearching the particular subject.

SUMMARY

This Summary is provided to introduce a selection of concepts in asimplified form that are further described below in the DetailedDescription. This Summary is not intended to identify key features oressential features of the claimed subject matter, nor is it intended tobe used as an aid in determining the scope of the claimed subjectmatter.

Embodiments of the present invention generally relate tocomputer-readable media and computerized methods for organizing searchresults based on a list of predefined task groups that attempt tocapture a collection of users' top common intents when issuing aparticular query. In one instance, the list of predefined task groups isidentified by analyzing patterns of user search behavior to select termsthat reflect popular user search intents with respect to a query orclass of queries. In variations of this method for identifying taskgroups, the selected terms may be ranked based on predeterminedparameters (e.g., terms that correspond to the greatest number ofentities stored in the data store) to produce an ordering, and declaringa set of the selected terms that are the highest ranked, based on theordering, the task groups.

By way of example only, with reference to a search query of “Audi,” thetop common intents of users who submit a query of “Audi” may be tolocate search results pertaining to “sales,” “parts,” “types,”“dealers,” “reviews,” “prices,” and “accessories.” These top commonintents may be aggregated from patterns of user search behavior that areassociated with previous user-initiated searches for “Audi” or for othercar brands. In other words, common intents of a user may be identifiedwith respect to a particular query (e.g., Audi), or may be identifiedwith respect to a class of queries (e.g., cars), where each specificquery in a class (e.g., Toyota, Mazda, BMW, and the like) correspond tothe same common user intents.

One or more terms that describe these common user intents are attachedto the user intents and designated as task groups. In addition, searchresults that are determined to be relevant to the task groups areassociated therewith. As such, when a query is issued (e.g., Audi), thesearch results are selected and arranged based on the task groups (e.g.,sales, parts, types, dealers, and the like). Further, this arrangementof the search results is rendered on a user interface (UI) display,thereby providing a user with an organized experience. Advantageously,this arrangement of search results in accordance with task groups isbased on a prediction of the user's intents when submitting the query;thus, the rendered arrangement of the search results is intuitive to theuser and promotes efficient narrowing of a search and enhancedidentification of a relevant search result.

DETAILED DESCRIPTION

The subject matter of the present invention is described withspecificity herein to meet statutory requirements. However, thedescription itself is not intended to limit the scope of this patent.Rather, the inventors have contemplated that the claimed subject mattermight also be embodied in other ways, to include different steps orcombinations of steps similar to the ones described in this document, inconjunction with other present or future technologies.

Accordingly, in one embodiment, the present invention relates tocomputer-executable instructions, embodied on one or morecomputer-readable media, that perform a method for automaticallyorganizing search results according to task groups. Initially, themethod includes, in embodiments, aggregating a gallery of entities intoa query class. Typically, the gallery of entities corresponds to queriesthat share a common categorization. At least one dictionary is assignedto the query class, where the dictionary includes a list of terms thatare drawn from one or more sources (e.g., data store communicativelycoupled to a search engine). The method further involves identifying thetask groups from the list of terms within the dictionary by utilizing aprocess. In an exemplary embodiment, the process for identifying thetask groups involves, at least, the steps of analyzing patterns of usersearch behavior to select one or more terms from the list of terms thatreflect popular user search intents, ranking the terms based onpredetermined parameters to produce an ordering, and based on theordering, declaring a set of the terms that are highest ranked withinthe ordering the task groups. These task groups may be persisted, atleast temporarily, by storing them on the computer-readable media inassociation with the query class.

In another embodiment, aspects of the present invention involve acomputerized method, implemented at a processing unit, for manipulatinga composition of a list of terms associated with a query class.Initially, the method involves a step of selecting a gallery of entitiesthat are compiled to form the query class. Generally, each entity in thegallery of entities corresponds to a query that shares a commoncategorization with other queries represented by other entities in thegallery of entities. A list of terms may be extracted from at least onedata store, where each term in the list of terms is associated with asearch refinement path of the query. In this instance, the queryincludes entities that reside in the selected gallery of entities.

At some point, a structured searchable database is scanned to identifyequivalences between terms within the list of terms and/or relevantterms that share a common categorization with the query class. In oneinstance, scanning the structured searchable database to identifyequivalences between terms within the list of terms includes theprocedures of mining the structured searchable database for redirectsthat indicate synonymous terms, ascertaining that the synonymous termsappear in the list of terms, and condensing the composition of the listof terms by removing one or more of the synonymous terms. In anotherinstance, scanning the structured searchable database to identifyrelevant terms that share a common categorization with the query classincludes the procedures of mining the structured searchable database fortopics that categorize the gallery of entities assembled to form thequery class, associating a score with the topics based upon a number ofentities in the gallery of entities that are related to the topic, andcomparing the score associated with each of the topics against eachother to distill a set of highest scoring topics from the topics. Basedon the highest scoring topics, the composition of the list of terms maybe expanded by incorporating terms categorized by the highest scoringtopics into the list of terms.

Accordingly, based on a scan of the structured searchable database, thecomposition of the list of terms is condensed or expanded by applyingthe equivalences or the relevant terms, respectively, to update the listof terms. Once the list of terms is updated, the original list of termsis replaced with the updated list of terms. Further, the updated list ofterms, in association with the query class, is written to a storagelocation on computer-readable media accessible by the processing unitfor subsequent access.

In yet another embodiment, the present invention encompasses one or morecomputer-readable media that has computer-executable instructionsembodied thereon that, when executed, perform a method for utilizingtask groups to automatically organize search results on a user-interface(UI) display. Generally, the method includes providing a plurality ofdictionaries. As discussed above, each of the plurality of dictionariesincludes a list of terms, where each term in the list of terms, at somepoint, helped refine a search for an entity within a gallery ofentities. Typically, each entity in the gallery of entities isassociated with the other entities in the gallery as they belong to thesame category. One or more terms from the list of terms, which reflectpopular user search intents of users over a predefined timeframe, areidentified. These one or more identified terms are promoted to taskgroups.

Once the task groups are established, the search results that areresponsive to a query are selected and arranged based on the taskgroups. In particular, a user-issued query may be received that iscomprised of search terms that map to an entity associated with one ormore of the plurality of dictionaries. Upon receiving the user-issuedquery, a dictionary from the plurality of dictionaries is selected andthe task groups associated with the selected dictionary are recognized.In one instance, selecting a dictionary involves the steps of reviewingthe list of terms comprising each of the plurality of dictionaries, and,upon review, targeting the dictionary that includes the list of termsthat are most frequently employed to narrow a search with theuser-issued query.

Search results that are responsive to the query are gathered inconjunction with each of the task groups, respectively. Eventually, apresentation device is instructed to render the search results on the UIdisplay. In one embodiments, the search results are displayed proximateto each of the task groups with which each of the search resultscorresponds, respectively. In one instance, the process of displayinginvolves the following steps: locating a portion of the search results,which are responsive to a search using the first of the task groups,below a heading that describes the first task group on the UI display;and locating a portion of the search results, which are responsive to asearch using the second of the task groups, below a heading thatdescribes the second task group on the UI display. In another instance,the process of displaying involves presenting a panel on the UI displaythat adjoins the organized search results. Typically, the panelpublishes a table of contents that enumerates the first and the secondtask groups.

Having briefly described an overview of embodiments of the presentinvention and some of the features therein, an exemplary operatingenvironment suitable for implementing the present invention is describedbelow.

Referring to the drawings in general, and initially to FIG. 1 inparticular, an exemplary operating environment for implementingembodiments of the present invention is shown and designated generallyas computing device 100. Computing device 100 is but one example of asuitable computing environment and is not intended to suggest anylimitation as to the scope of use or functionality of the invention.Neither should the computing device 100 be interpreted as having anydependency or requirement relating to any one or combination ofcomponents illustrated.

The invention may be described in the general context of computer codeor machine-useable instructions, including computer-executableinstructions such as program components, being executed by a computer orother machine, such as a personal data assistant or other handhelddevice. Generally, program components including routines, programs,objects, components, data structures, and the like, refer to code thatperforms particular tasks or implements particular abstract data types.Embodiments of the present invention may be practiced in a variety ofsystem configurations, including handheld devices, consumer electronics,general-purpose computers, specialty computing devices, etc. Embodimentsof the invention may also be practiced in distributed computingenvironments where tasks are performed by remote-processing devices thatare linked through a communications network.

With continued reference to FIG. 1, computing device 100 includes a bus110 that directly or indirectly couples the following devices: memory112, one or more processors 114, one or more presentation components116, input/output (I/O) ports 118, I/O components 120, and anillustrative power supply 122. Bus 110 represents what may be one ormore busses (such as an address bus, data bus, or combination thereof).Although the various blocks of FIG. 1 are shown with lines for the sakeof clarity, in reality, delineating various components is not so clearand, metaphorically, the lines would more accurately be grey and fuzzy.For example, one may consider a presentation component such as a displaydevice to be an I/O component. Also, processors have memory. Theinventors hereof recognize that such is the nature of the art andreiterate that the diagram of FIG. 1 is merely illustrative of anexemplary computing device that can be used in connection with one ormore embodiments of the present invention. Distinction is not madebetween such categories as “workstation,” “server,” “laptop,” “handhelddevice,” etc., as all are contemplated within the scope of FIG. 1 andreference to “computer” or “computing device.”

Computing device 100 typically includes a variety of computer-readablemedia. By way of example, and not limitation, computer-readable mediamay comprise Random Access Memory (RAM); Read Only Memory (ROM);Electronically Erasable Programmable Read Only Memory (EEPROM); flashmemory or other memory technologies; CDROM, digital versatile disks(DVDs) or other optical or holographic media; magnetic cassettes,magnetic tape, magnetic disk storage or other magnetic storage devices;or any other medium that can be used to encode desired information andbe accessed by computing device 100.

Memory 112 includes computer-storage media in the form of volatileand/or nonvolatile memory. The memory may be removable, nonremovable, ora combination thereof. Exemplary hardware devices include solid-statememory, hard drives, optical-disc drives, etc. Computing device 100includes one or more processors that read data from various entitiessuch as memory 112 or I/O components 120. Presentation component(s) 116present data indications to a user or other device. Exemplarypresentation components include a display device, speaker, printingcomponent, vibrating component, etc. I/O ports 118 allow computingdevice 100 to be logically coupled to other devices including I/Ocomponents 120, some of which may be built in. Illustrative componentsinclude a microphone, joystick, game pad, satellite dish, scanner,printer, wireless device, etc.

In some embodiments, the computing device 100 of FIG. 1 is configured toimplement various aspects of the present invention. In one instance,these aspects relate to providing a user with a new organized searchexperience. Generally, providing an organized search experience involvesorganizing search results, in response to a query, such that when theuser submits an initially high level of the query (e.g., Audi), theprocess breaks down the search results to organized components that fitunder a predefined number of task groups (e.g., Sales, Parts, Types,Dealers, Reviews, Price, Accessories, and the like).

As used herein, the phrase “task groups” is not meant to be limiting,but broadly describes top common intents of individual users, or acollection of users, that have submitted a particular query. The topcommon intents and/or tasks of users pertain to the most popular goalsthe users want to achieve when submitting a high level of query. By wayof example only, popular goals that are associated with the high-levelquery of “Seattle” may be to determine the “current weather in Seattle”or to find “restaurants in Seattle.” As such, these popular goals orintents/tasks are established as the task groups for the query“Seattle.” In similar embodiments of the present invention, discussedmore fully below, the popular goals maintained by users, upon entering aparticular query, are stored as task groups that are associated with (a)the particular query, (b) a collection of similarly themed queries(e.g., query class), and/or (c) each of the queries comprising the queryclass.

In another embodiment, task groups refer to general categories within aquery class that divide into logical baskets the search results that areassociated with queries of the query class. By way of example, thegeneral categories of a search for “Jennifer Lopez” may include“albums,” “images,” and “awards,” but also may include websites that arefrequently accessed to discover a biography of Jennifer Lopez. Thesewebsites may relate to “instant answers” that are artificially createdby the search engine 275, or other entity, to help a user quickly andefficiently refine a high-level query. As such, the general categoriesfacilitate organizing the instant answers and search results to providea user with a comprehensive selection of possible refinement paths toutilize when narrowing the high-level query. Thus, arranging the searchresults by categories, instead of simply arranging the search results byrelevance to a query, help the user target a group of search resultsthat correspond to his/her true intent behind entering the high-levelquery.

The phrase “query class,” as utilized herein, is not meant to belimiting, but may expansively encompass any set, list, manifest,aggregation, and/or index of terms or phrases that collectively share atleast one common characteristic. In an exemplary embodiment, the queryclass represents a collection of previously issued queries and othercomplimentary terms that each relate to a particular theme. By way ofexample, with reference to the common theme of “cars,” the query classrepresents such previously issued queries as “Audi,” “Nissan,”“Porsche,” and “Mercedes Benz.” These previously issued queries, termsthat compliment the queries, instant answers, and any other items thatrelate to a particular theme are referred to herein as “entities.”Accordingly, the collection of entities that share the commoncharacteristic of a particular query class are referred to herein as a“gallery of entities.” In a particular instance, the gallery of entitiesbroadly refers to a set of queries in a similar class that share thesame intent or task maintained by a user who submits a query within theset of queries.

Accordingly, as discussed above, each of the task groups established fora query class may be used to categorize the search results for eachentity within the entity gallery. As such, applying the task groupsconsistently across the entities in a gallery promotes a categorizedsearch experience that delivers a consistent organization of searchresults within a particular query class. By way of example, if the themeof the query class is “cars,” then the entities in the entity gallery,in some fashion, relate to aspects or models of cars. With furtherreference to this example, if the user submits a query that correspondsto any entity in the gallery of entities associated with the “cars”query class, the query will produce a consistent list of task groups(e.g., Sales, Parts, Types, Dealers, Reviews, Price, Accessories, andthe like) regardless of the entity matching the query. That is, forevery query that includes as a component an aspect or model of car, thesame consistent organized experience is delivered via the constantutilization of task groups for that query class. In other embodiments,the list of task groups is varied between different entities by changingthe ordering or the composition of the list of task groups.

Further lists of terms may be associated with each query class and eachgallery of entities. This list of terms, or “dictionary,” encompassesterms, phrases, and alphanumeric strings that are derived from pastsearches, or, at least, are modifiers of past searches. In one instance,the dictionary includes terms and phrases that are associated withsearch results that are responsive to entities within the gallery ofentities (e.g., queries that share a common characteristic)corresponding to a query class. In one embodiment, the list of termsthat comprise the contents of a dictionary are generated from structureddata feeds compiled by a search engine. In another embodiment, the listof terms is extracted from distributed data sources and imported to asearch engine.

Although two different configurations of aggregating a list of termshave been described, it should be understood and appreciated by those ofordinary skill in the art that other types of suitable procedures forproducing and for updating a list of terms may be used, and thatembodiments of the present invention are not limited to those exemplarymechanisms for aggregating a list of terms described herein. Forinstance, an administrator of a search engine may deliberatelymanufacture the list of terms for a certain query class with minimalreliance on another source of user search behavior.

A categorization process for automatically generating a set of taskgroups for a query class and for organizing search results on a UIdisplay based on the task groups will now be discussed with reference toFIG. 2. In particular, FIG. 2 depicts a block diagram that illustratesan exemplary system architecture 200 of a distributed computingenvironment, suitable for use in implementing embodiments of the presentinvention. Generally, implementing embodiments of the present inventionrelate to ascertaining task groups from patterns of search behavior andto applying the task groups when presenting search results to a user(e.g., rendering search results in a UI display). It should beunderstood and appreciated that the exemplary system architecture 200shown in FIG. 2 is merely an example of one suitable computingenvironment and is not intended to suggest any limitation as to thescope of use or functionality of the present invention. Neither shouldthe exemplary system architecture 200 be interpreted as having anydependency or requirement related to any single component or combinationof components illustrated therein.

Initially, the exemplary system architecture 200 includes a clientdevice 210, data stores 230, a structured searchable database 201, aserver 250, and a network 208 that interconnects each of these items.Each of the client device 210, the data stores 230, the structuredsearchable database 201, and the server 250, shown in FIG. 2, may takethe form of various types of computing devices, such as, for example,the computing device 100 described above with reference to FIG. 1. Byway of example only and not limitation, the client device 210 and/or theserver 250 may be a personal computer, desktop computer, laptopcomputer, consumer electronic device, handheld device (e.g., personaldigital assistant), various servers, processing equipment, and the like.It should be noted, however, that the invention is not limited toimplementation on such computing devices but may be implemented on anyof a variety of different types of computing devices within the scope ofembodiments of the present invention.

Typically, each of the devices 210 and 250 includes, or is linked to,some form of a computing unit (e.g., central processing unit,microprocessor, etc.) to support operations of the component(s) runningthereon (e.g., task group identifying component 205, query classcomposer 255, instant answers component 258, and the like). As utilizedherein, the phrase “computing unit” generally refers to a dedicatedcomputing device with processing power and storage memory, whichsupports operating software that underlies the execution of software,applications, and computer programs thereon. In one instance, thecomputing unit is configured with tangible hardware elements, ormachines, that are integral, or operably coupled, to the devices 210 and250 to enable each device to perform communication-related processes andother operations (e.g., capturing a dictionary 231 from a data store230, generating task groups 270, and the like). In another instance, thecomputing unit may encompass a processor (not shown) coupled to thecomputer-readable medium accommodated by each of the devices 210 and250.

Generally, the computer-readable medium includes physical memory thatstores, at least temporarily, a plurality of computer softwarecomponents that are executable by the processor. As utilized herein, theterm “processor” is not meant to be limiting and may encompass anyelements of the computing unit that act in a computational capacity. Insuch capacity, the processor may be configured as a tangible articlethat processes instructions. In an exemplary embodiment, processing mayinvolve fetching, decoding/interpreting, executing, and writing backinstructions (e.g., reconstructing the list of terms within thedictionary 231 upon expanding or condensing the terms).

Also, beyond processing instructions, the processor may transferinformation to and from other resources that are integral to, ordisposed on, the devices 210 and 250. Generally, resources refer tosoftware components or hardware mechanisms that enable the devices 210and 250 to perform a particular function. By way of example only, theresources accommodated by the server 250 may include one or more of thefollowing: a task group identifying component 205, a query classcomposer 255, a dictionary component 256, an instant answers component258, a search engine 275, and an organizing component 280.

The client device 210 may include an input device (not shown) and apresentation device 215. Generally, the input device is provided toreceive input(s) affecting, among other things, a presentation of thesearch results in a browser window 225 surfaced at a UI display area220. Illustrative devices include a mouse, joystick, key pad,microphone, I/O components 120 of FIG. 1, or any other component capableof receiving a user input and communicating an indication of that inputto the client device 210. By way of example only, the input devicefacilitates entry of a query and controls the location of a selectiontool on the search results responsive to the query.

In embodiments, the presentation device 215 is configured to renderand/or present the UI display 220 thereon. The presentation device 215,which is operably coupled to an output of the client device 210, may beconfigured as any presentation component that is capable of presentinginformation to a user, such as a digital monitor, electronic displaypanel, touch-screen, analog set top box, plasma screen, audio speakers,Braille pad, and the like. In one exemplary embodiment, the presentationdevice 215 is configured to present rich content, such as the browserwindow 225 that includes a display area populated with search results(e.g., digital images). In another exemplary embodiment, thepresentation device 215 is capable of rendering other forms of media(e.g., audio signals). In yet another exemplary embodiment, thepresentation device 215 may present a portion of the search results inproximity with one of the set of task groups 270, as more fullydiscussed below.

The data store(s) 230 are generally configured to store informationassociated with a user-submitted query and/or data generated fromprevious query results and user interaction therewith, discussed below.In various embodiments, such information may include, withoutlimitation, the dictionary 231 that includes a list of terms from whichthe task groups 270 are identified, recorded user search behavior (e.g.,query logs, related searches list, etc.), and other information 235 thatpertains to embodiments of the present invention. In addition, the datastore(s) 230 may be configured to be searchable for suitable access ofthe stored information 235. For instance, the data store(s) 230 may besearchable for one or more user-initiated queries associated with anentity of the gallery of entities. It will be understood and appreciatedby those of ordinary skill in the art that the information stored in thedata store(s) 230 may be configurable and may include any informationrelevant to the generation and maintenance of the dictionaries, galleryof entities, task groups, and organization of the search results. Thecontent and volume of such information are not intended to limit thescope of embodiments of the present invention in any way. Further,though illustrated as single, independent components, the data store(s)230 may, in fact, be a plurality of databases, for instance, a databasecluster, portions of which may reside on the client device 210, theserver 250, the structured searchable database 201, another externalcomputing device (not shown), and/or any combination thereof.

This exemplary system architecture 200 is but one example of a suitableenvironment that may be implemented to carry out aspects of the presentinvention and is not intended to suggest any limitation as to the scopeof use or functionality of the invention. Neither should the illustratedexemplary system architecture 200 be interpreted as having anydependency or requirement relating to any one or combination of thecomputing devices 210 and 250, the storage devices 201 and 230, andcomponents 205, 255, 256, 258, 275, and 280 as illustrated. In someembodiments, one or more of the components 205, 255, 256, 258, 275, and280 may be implemented as stand-alone devices. In other embodiments, oneor more of the components 205, 255, 256, 258, 275, and 280 may beintegrated directly into the server 250, or on distributed nodes thatinterconnect to form the server 250. It will be understood by those ofordinary skill in the art that the components 205, 255, 256, 258, 275,and 280 (illustrated in FIG. 2) are exemplary in nature and in numberand should not be construed as limiting.

Accordingly, any number of components may be employed to achieve thedesired functionality within the scope of embodiments of the presentinvention. Although the various components of FIG. 2 are shown withlines for the sake of clarity, in reality, delineating variouscomponents is not so clear, and, metaphorically, the lines would moreaccurately be grey or fuzzy. Further, although some components of FIG. 2are depicted as single blocks, the depictions are exemplary in natureand in number and are not to be construed as limiting (e.g., althoughonly one presentation device 215 is shown, many more may becommunicatively coupled to the client device 210).

Further, the devices of the exemplary system architecture may beinterconnected by any method known in the relevant field. For instance,the server 250 and the client device 210 may be operably coupled via adistributed computing environment that includes multiple computingdevices coupled with one another via one or more networks 208. Inembodiments, the network 208 may include, without limitation, one ormore local area networks (LANs) and/or wide area networks (WANs). Suchnetworking environments are commonplace in offices, enterprise-widecomputer networks, intranets, and the Internet. Accordingly, the networkis not further described herein.

In operation, the components 205, 255, 256, 258, 275, and 280 aredesigned to perform a process that includes, at least, the steps ofselecting task groups 270 from the dictionary 231, associating the taskgroups 270 with one or more entities in the gallery of entities(associated with both the dictionary 231 and a query class), and sortingand exposing the search results based on the task groups 270. Initially,the dictionary component 256 is responsible for generating and updatinga list of terms, or dictionary 231, that is associated with a particularquery class. In one instance, with respect to generating the list ofterms, the dictionary 231 is pulled from a source external to the server250, such as the data store(s) 230. In another instance, the dictionary231 is compiled from data feeds that pass through the search engine 275.

Further, the dictionary component 256 is configured to update the listof terms within the dictionary 231. In on sense, updating the dictionary231 involves expanding the list of terms by discovering terms that areequivalent to the terms already compiled in the dictionary. Generally,expanding the list of terms involves the steps of scanning thestructured searchable database 210 to identify relevant terms that sharea common categorization with the query class (associated with thedictionary), and expanding the composition of the list of terms byapplying the relevant terms to update the list of terms. The updatedlist of terms 241 may be used to replace the current list of termswithin the dictionary 231. The procedure of scanning the structuredsearchable database 201 to identify relevant terms that share a commoncategorization with the query class initially includes the step ofmining the structured searchable database 201 for topics that categorizethe gallery of entities assembled to form the query class. Inembodiments, mining the structured searchable database 231 may compriseemploying a dictionary-expansion algorithm that crawls through thestructured searchable database 201, or other databases, to find termsthat are similar to terms in the current list of terms. With referenceto FIG. 2, the information exchanged between the dictionary component256 and the structured searchable database 201, when mining, is depictedby reference numeral 240.

In one instance, the structured searchable database 201 is theWikipedia® website. In this instance, the dictionary-expansion algorithminspects the Wikipedia® website to find categories therein that sortsearchable words. Those searchable words that are sorted into categoriesthat are relevant to the list of terms are incorporated into the list ofterms, thereby building a more comprehensive dictionary.

By way of example, if the query class is “musicians” and the list ofterms within the dictionary 231 substantially includes the names ofindividual musicians and musical groups, a dictionary-expansionalgorithm may be employed to expand the dictionary 231 associated withmusicians by pulling the names of other musicians and musical groupsfrom Wikipedia®. Initially, data within Wikipedia® is scanned tounderstand what categories therein mainly feature musicians. Then, ascore is associated with each of the topics upon determining an entityof the gallery of entities or a term of the list of terms is categorizedby that topic. For each additional entity or gallery that correspondswith that topic, the associated score is incrementally increased. Forinstance, if the query class relates to musicians and the term “JenniferLopez” of the dictionary associated with musicians is used tointerrogate Wikipedia®, it is likely that the topic “AmericanActor/Singers” will be identified as being relevant. As such, a scoreassociated with this topic will be incremented because thedictionary-expansion algorithm considers this topic to be related to alist of other singers. Then, another musician (e.g., Prince) may be usedto interrogate the topics of Wikipedia®.

Upon applying each term in the dictionary 231 to Wikipedia®, the resultwill be a set of topics that each has a score associated therewith.These scores may be compared against each other to distill a set ofhighest scoring topics from the topics. Accordingly, a composition ofthe list of terms may be expanded by incorporating terms categorized bythe highest scoring topics into the list of terms. For instance, theterm “Madonna” may not be initially included in the dictionary, but maybe associated with one of the highest scoring topics of the structuredsearchable database 201 (e.g., American Actor/Singers). Accordingly, thedictionary 231 will likely be expanded to include the musician Madonnaupon exercising the dictionary-expansion algorithm.

Although Wikipedia® is used as an exemplary model for describing theexpansion of the list of terms within a dictionary 231, it should beunderstood and appreciated that the structured searchable database 201may be practiced by various components which are different from thespecific illustrated embodiment. Therefore, it is emphasized that theinvention is not limited only to its embodiment pertaining toWikipedia®, but is embracing of a wide variety of mechanisms which fallwithin the spirit of the following claims.

Besides updating the dictionary 231 by way of expansion, the dictionary231 may also be updated by condensing the list of terms. In oneembodiment of condensing, the dictionary component 256 may be employedto scan the structured searchable database 201 in order to identifyequivalences between terms within the list of terms. Scanning caninclude mining the structured searchable database 201 for redirects thatindicate synonymous terms. For a given term, “redirects” facilitatefinding the various ways users search for a particular entity.Accordingly, redirects within a database provide an indication that theterms connected by the redirect are equivalent terms—at least from theperspective of an administrator maintaining the database. By way ofexample, if the structured searchable database 201 is Wikipedia® and theterm from the dictionary 231 being tested via Wikipedia® is “J Lo,” aredirect may cause a webpage referencing “Jennifer Lopez” to surface. Assuch, this redirect signifies that “J Lo” and “Jennifer Lopez” havesimilar meanings to users who conduct a search for thatmusician/actress.

Next, upon detecting a redirect and identifying synonymous termsassociated therewith, the dictionary component 256 may ascertain thatthe identified synonymous terms appear in the list of terms. If both ofthe synonymous terms do appear in the dictionary, the composition of thelist of terms is condensed by removing one of the synonymous terms andby linking the removed, or extraneous, term to the retained term. Inother words, the synonymous terms are stitched together to reduceredundancy.

In another embodiment of condensing, an overlap between terms in thedictionary 231 is recognized by the dictionary component 256 uponreviewing click-through behavior of users. As discussed above, thisclick-through behavior may be extracted from one or more of the datastores 230, which remotely persists user search behavior 232. In thisembodiment of condensing, the historical click-through data generated byeach entity in the gallery of entities is analyzed. Based on theanalysis, terms in the list of terms that are invoked at a similar clickdistribution are identified. In one instance of identifying, acorrelation factor is assigned to pairs or groups of terms whose clickdistributions exhibit a high level of correlation. This high level ofcorrelation indicates that the terms overlap in concept and areconsidered equivalent by users. As such, the composition of the list ofterms may be condensed by removing one or more of the terms identifiedas overlapping another term.

In still another embodiment of condensing, generic terms are identifiedand removed from the dictionary. Initially, identifying generic termsinvolves analyzing patterns across queries, where the queries may bedrawn from the user search behavior 232. Typically, the queries that arereviewed include as a component the entities from the gallery ofentities associated with the dictionary. Based on the analysis, termsare identified as generic when they appear frequently in the queries inconjunction with entities from the entity gallery. Specifically, termsare generic when they frequently modify multiple and differing entitieswithin a query. By way of example, if the term “biography” is identifiedin queries that are associated with many various musicians, such as“Jennifer Lopez,” “Prince,” and the like, then “biography” may beidentified as generic. Once identified, the composition of the list ofterms is condensed by removing the generic, or extraneous, term(s).

Referring now to the query class composer 255 residing on the server250, the process of building a query class 260 will now be discussed.Generally, as discussed above, the query class broadly represents acollection of queries that share a common theme, characteristic, and/orattribute. For instance, the queries that include as a component“Backstreet Boys,” “Madonna,” and “Dave Matthews” all share the commontheme of being musicians and, thus, would be grouped together to form aquery class by the query class composer 255. These queries that areinspected and grouped may be mined from any database (e.g., structuredsearchable database 201, data stores 230, etc.), local or remote, thatis accessible to the server 250.

The task group identifying component 205 is generally configured toreceive the query class 260 (provided by the query class composer 255)and the updated dictionary 241 (provided by the dictionary component256) and generate a set of task groups 270 for each of the query classes260 utilizing the list of terms within the updated dictionary 241. In anexemplary embodiment, an overall method for generating task groups 270involves, at least, the following steps: (a) analyzing patterns of theuser search behavior 232 to select one or more terms from the list ofterms that reflect popular user search intents; (b) ranking the termsbased on predetermined parameters to produce an ordering; and (c) basedon the ordering, identifying a set of the terms that are highest rankedas the task groups 270. These task groups 270 may be stored inassociation with the appropriate query class 260 on computer-readablemedia accommodated by the server 250 or on a remote physical memory.

In one embodiment, the step of analyzing patterns of the user searchbehavior 232 may involve enumerating the most common modifiers (e.g.,suffix and prefix) that appear in queries either before or afterentities from the gallery of entities associated with the query class260. For instance, enumerating may include counting the number of timesa modifier is used as a query suffix or prefix to the entities in thegallery. If the count is comparably high when compared against othermodifiers being examined, then the modifier is earmarked as a candidatefor becoming a task group 270. By way of clarification, “prefixes” aretypically modifiers (e.g., terms, phrases, text strings, alphanumericalcharacters, etc.) that precede one or more terms that map to at leastone of the entities in the query class 260. On the other hand,“suffixes” are typically modifiers that follow one or more terms thatmap to at least one of the entities in the query class 260. Further,modifiers may correspond to one or more terms in the dictionary 231assigned to the query class 260.

By way of example, with reference to the queries “parts for Audi S8”(where parts is a prefix modifier of the entity Audi S8) and “Audi S8parts” (where parts is a suffix modifier of the entity Audi S8), thecount for the modifier “parts” would be increment by two. Accordingly,in this example, the term “parts” reflects a common, or top, task thatusers desire to perform when searching within the query class of “cars.”In operation, search results that are responsive to a query (e.g.,“Porsche”) associated with the query class of “cars” will be groupedbased on the task group of “parts,” among other task groups relevant to“cars.”

In another embodiment, as opposed to tracking a count of usage for amodifier of an entity, a frequency of appearance in queries as a suffixor prefix may be compiled. Accordingly, based on the frequency, the mostcommon modifiers (e.g., prefixes and suffixes) may be identified. Statedanother way, the method for identifying the task groups 270 usingfrequencies of appearance may include the following steps: accessing aquery log (e.g., user search behavior 232) that includes a plurality ofuser-initiated queries corresponding to the entities designated as partof the query class 260; analyzing components of each of theuser-initiated queries to identify one or more terms that map to one ofthe entities and to identify modifiers of these terms; compiling a setof modifiers that most frequently occur as a component within theuser-initiated queries; and establishing the most-frequently-occurringset of modifiers as the task groups 270. These most-frequent modifiersboth capture and indicate a strong association between the modifier andthe tasks or intents commonly performed by users during a search. Assuch, the task groups 270 that are derived from the most-frequentmodifiers may apply to all, or at least a large portion, of the entitiesor queries that are associated with the query class 260. Further,because any number of queries may be inspected to ascertain themost-frequent modifiers, this process of identifying the top task groups270 is scalable (e.g., based on computing resources available).

Upon identifying the prefixes and the suffixes that are used inconjunction with an entity in a query, these modifiers may be used tocollapse and consolidate the list of terms within the dictionary 231,thereby removing redundant words from the list of terms. Initially,collapsing the dictionary 231 may involve identifying modifiers that arecommonly employed to refine a search with a particular entity from thegallery of entities. By way of example, the modifiers “photos” and“images” may be determined to commonly refine a search of a particularentity, such as “Jennifer Lopez.” Accordingly, these modifiers may beassociated with each other, or clustered. These clusters represent asimilar intent of users when searching for a digital representation ofJennifer Lopez. Then, the associated modifiers (prefixes and suffixes)may be moved to a single entry of the dictionary 231 in order tocollapse the list of terms. In another instance, one of the modifiersmay be identified as extraneous and removed from the list of terms.

In a second exemplary embodiment of identifying the top task groups 270,the process of identifying relies heavily on historical user reactionsto the results of a query. This second embodiment of the task group 270identification process involves, but is not limited to, the followingsteps: accessing a related-searches list (e.g., the user search behavior232); and performing a session analysis utilizing the related-searcheslist. Typically, the related-searches list includes terms from thedictionary 241 that are offered to users while conducting a search withan entity from the gallery of entities. In instances, the process ofperforming a session analysis involves compiling historical reactions ofthe users when selecting one or more of the terms in therelated-searches list, identifying a set of the terms in therelated-searches list that have most-frequently received a positivereaction from the users, and establishing the identified set of terms asthe task groups 270.

With reference to the step of compiling historical reactions of theusers when selecting terms appearing in the related-searches list, anoccurrence of a user-selection indicates that the users are attemptingto narrow their search by incorporating terms from the dictionary 231into a query. Further, with reference to the step of identifying theterms that have most-frequently received positive reaction from users,the “positive reaction” may include a click-through on a term from therelated-searches list, a selection on a follow-on webpage rendered inresponse to the click-through, another type of user interaction whennavigating the Internet or intranet, and/or any combination of theseactions.

In another embodiment, the step of performing session analysis includesexamining previous queries that are not limited to suffixes and prefixesof an entity in the gallery. In one instance, session analysis isperformed with sequential queries, which are typically pairs of queriesthat users issued in sequence (e.g., second query is issued after afirst query by a particular user within a limited time window). In otherinstances, the sequential queries may be a string of any number ofqueries, where the number is predetermined by the task group identifyingcomponent 205. In some instances, these related pairs of queries may berecovered from a related-searches list that is used to offer users achoice of related searches in response to a query. These sequentialqueries may be identified and aggregated over a multitude of users inorder to gain a comprehensive perspective of searching preferences,intents, and common tasks. Accordingly, the sequential pairs provide aninsight as to what users commonly search for, and what is selected orengaged with during a particular search or refinement path of thesearch.

By performing a session analysis that includes examining user behaviorwith relation to a search refinement (e.g., clicking on a term, clickingon a second page, and the like), it is possible to determine thosetriggered query suggestions within a related-searches list that are mostpopular and/or relevant to a query topic. These popular querysuggestions, which also appear in the list of terms, may be aggregatedacross the available session data to compile a most-common set ofrelated searches from the queries within the gallery.

In embodiments, a related-searches model is used to rank the resultingset of related searches. In one instance, the related-searches modelranks based on user feedback in a session log and normalizes the rankedrelated searches to produce a set of task groups 270 within the queryclass 260. This ranking may be based on how likely a user is toclick-through a suggested related search, as described above. As such,the related-searches model is able to predict the value of a relatedsearch to a user issuing a particular query based how likely a user isto select an initial suggested related search and/or how likely the useris to then click on a subsequently suggested related search surfaced bythe initial related search (e.g., calculating the click-probability foreach suggested related search offered in response to, or relevant, to aquery).

Typically, the value of each related search to a user is recorded as ascore. By way of example, the score for a particular related search maybe incremented by one point if an initial click-through is received atthe related search upon being offered to a user. Alternatively, thescore of the related search may be incremented by ten points if afollow-on page or additional related search is selected upon receivingthe initial click-through. In another instance of scoring a relatedsearch, the selection on the follow-on page is generally weighted higherthan, or equal to, the weight attached to the click-through. In yetanother instance, the score for a related search is penalized forsurfacing a follow-on page that does not receive a follow-on click. Assuch, this score (e.g., number of many times a user selects the relatedsearch “parts” upon typing the query “Audi”), which is used to rank therelated searches to determine the task groups 270 therefrom, serves as atrustworthy indicator of user intents when performing a search of theparticular query within the query class 260.

Although two different events (e.g., click-through and selection afterclick-through) for gauging a value of a related search to a user havebeen described, it should be understood and appreciated by those ofordinary skill in the art that other types of suitable events thatprovide an indication of user intents when searching may be used, andthat embodiments of the present invention are not limited to thoseparticular events described herein.

Once the most common modifiers or related searches are identified by theprocesses described above, the modifiers or related searches are rankedbased on predetermined parameters, and the highest ranking modifiers orrelated searches are selected as the task groups 270. In one instance,the “predetermined parameters” pertain to the score determined for eachrelated search, which captures a strength of the positive reaction fromthe users. In another instance, “predetermined parameters” pertain to anumber of entities in the gallery that each term in the dictionary 231modifies, as a prefix or suffix, within the inspected queries. Althoughtwo different configurations of the predetermined parameters have beendescribed, it should be understood and appreciated by those of ordinaryskill in the art that other types of suitable factors may be used rankthe modifiers or related searches, and that embodiments of the presentinvention are not limited to those predetermined parameters describedherein. For instance, the scores of the related searches, or the numberof times a modifier is used, may be employed to compile a set ofrelevant related searches or modifiers that reflect top intents, while athird method may be used to rank those related searches or modifierswithin the set.

In other embodiments, the task group identifying component 205 isresponsible for filtering the task groups 270 (identified above)utilizing criteria, where the task groups 270 that satisfy the criteriaare persisted while the task groups 270 that do not meet the criteriaare disqualified. In one instance, the criteria pertains to ascertainingwhether the task group includes a timeframe component. By way ofexample, if the task group “2009 Audi” is identified, it is disqualifiedfor having the timeframe component of “2009.” As a general rule,timeframe components are disqualified because they become obsoleterapidly and often detract from more relevant task groups.

In another instance, the criteria pertains to ascertaining whether thetask group includes as a component an entity from the gallery ofentities aggregated to form the query class. By way of example, if thetask group “Parts” is identified, it is disqualified for not includingan entity from the gallery associated with the query class “cars.”However, with continued reference to this example, the task group “Audiparts” would not be filtered. As a general rule, the modifier should bepaired with an entity to ensure that a search executed within the taskgroup returns search results that relate to the query class, as opposedto a overbroad search that is responsive to just the modifier (e.g.,searching just “parts” as a query may collect search results that do notcorrespond with “Audi” or “cars”).

Once the set of task groups 270 is identified, ranked, and filtered, thetop task groups 270 are associated with one or more entities of queriesthat make up the query class 260, or are associated with the query classitself. When the task groups 270 are associated with an individualentity of the gallery, the search results that are responsive to a querythat include the entity are organized based on task groups 270. However,when another entity in the query class 260 is included in a query, asearch based on that query may generate search results that areorganized according to a different set of task groups 270. When the taskgroups 270 are associated with the query class 260, the search resultsthat are responsive to a query comprising any entity in the query class260 will by similarly organized based on one set of task groups 270.Generally, the task groups 270 are assigned to an entity whenentity-specific historical search data was used to generate the taskgroups 270, while the task groups 270 are assigned to the query class260 when category-wide historical search data was used to generate thetask groups 270.

In one instance, the process for assigning the task groups 270 to anentity that is a member of the query class 260 includes the steps ofidentifying the task groups 270 from the list of terms within theupdated dictionary 241 for the entity of the gallery of entities, andranking the task groups 270 associated with the entity based on thepredetermined parameters. Accordingly, the task groups 270 associatedwith a first entity of the gallery of entities may vary from the taskgroups 270 associated with a second entity of the gallery of entitiesfor the same query class 260.

In another instance, the process for assigning the task groups 270 to anentity that is a member of the query class 260 includes the step ofrecognizing that the entity in the gallery of entities lacks sufficientuser search behavior to derive the popular user search intents at a highlevel of accuracy (e.g., insufficient history of click-throughs orsearch data to accurately predict the top task groups 270). Uponrecognizing there is insufficient historical user behavior associatedwith the entity, the process for assigning the task groups 270 to theentity may further include the step of applying the task groups 270established for another entity in the gallery of entities to therecognized entity. By way of example, some obscure musician may berepresented by an entity in a gallery of entities associated with thequery class of “musicians.” If the task group identifying component 205recognizes that queries that included the obscure musician as acomponent were infrequent or generated inconsistent user reactions torelated searches, task groups from another, more popular, musician inthe query class of “musicians” may be applied to the obscure musician.

In one instance, applying involves supplanting the obscure musician'stask groups with those of another musician. In another instance,applying includes blending some of the obscure musician's task groupswith task groups associated with another musician, or associated withthe query class of “musicians,” to form a conglomerate set of taskgroups. In forming the conglomerate set of task groups, the task groupsassociated with each entity may be blended based on a weighting (e.g.,derived from an amount of supportive search history, confidence in theunderlying computation of the task groups, etc.). In embodiments, alogistic regression model may be used to facilitate blending, where thelogistical regression model analyzes the historical impressions andsearch behavior supporting the selection of each task group, andweighting the task groups based on the analysis.

Moving on to the answers component 258, a discussion of the procedurefor generating instant answers 259 will follow immediately below.“Instant answers” 259 as used herein, generally encompass those searchresults and/or task groups that are artificially created or deliberatelyselected in response to a query, as opposed to web-generated results. Byway of example, an instant answer to a search for “Jennifer Lopez” maybe a task group of “photos” with content items including digital imagesassociated therewith. Accordingly, the instant answer 259 may be a taskgroup within the set of top task groups 270 that is placed thereintentionally (outside the processes for selecting the task groups 270outlined above). In one instance, an administrator of the server 250 maymanually place the instant answer 259 within the set of top task groups270. In another instance, a program running on the server 250 mayautomatically place the instant answer 259 within the set of top taskgroups 270 in response to detecting certain conditions. Generally, theinstant answer 259, like the task groups 270, reflects common intents ofusers when conducting a search with a specific query.

The search engine 275 is generally configured to receive a query 285from the client device 210 and provide search results 290 to anorganizing component 280. Further, in one instance, the search engine275 is designed for searching for information on the Internet forgathering Internet search results in response to the user-submittedquery 285 that may be submitted through a website. In one embodiment,the search engine 275 includes one or more web crawlers that mineavailable data (e.g., newsgroups, databases, the data stores 230, oropen directories) accessible via the Internet and build a tablecontaining web addresses along with the subject matter of web pagesidentified as the search results 290 that are relevant to search termswithin the user-submitted query 285. The search engine 275 may beaccessed by Internet users through a web-browser application running onthe client device 210. Accordingly, the users may conduct an Internetsearch by submitting search terms at a query-entry area on the UIdisplay 220 presented on the web-browser application that is associatedwith the search engine 275. Further, the search engine 275 may thenretrieve the search results 290 that match the user's search terms inthe query 295.

In embodiments, the organizing component 280 is configured to receivethe query 285 issued by the user and select the set of top task groups270 based on the query 285. In one instance, selecting the set of toptask groups 270 involves a procedure comprising the steps of receivingthe user-issued query 285, composed of search terms that map to anentity associated with one or more query classes, and, incident toreceiving the user-issued query 285, selecting the query class 260 fromthe query classes, and recognizing the task groups 270 associated withthe selected query class 260. Typically, the step of selecting the queryclass 260 from the query classes includes reviewing the entities in thegallery associated with each of the query classes, and, upon review,targeting the query class 260 that reflects a gallery of entities thatare most frequently associated with the search terms within theuser-issued query 285.

Additionally, in embodiments, the organizing component 280 is configuredto receive the search results 290 gathered by the search engine 275 thatare responsive to the query 285, and to receive the instant answers 259related to the query 285 from the instant answers component 258. Thesesearch results 290 and instant answers 259 are combined and organizedutilizing the set of top task groups 270. Next, the organizing component280 is configured to instruct the presentation device 215 to render onthe UI display 220 the organized search results and instant answers 295proximate to each of the task groups 270 with which each of the searchresults 290 or instant answers 259 corresponds, respectively.

Referring to FIG. 8, the process of rendering the organized searchresults and instant answers 295 proximate to each of the task groups 270will now be discussed. Generally, FIG. 8 is an illustrative screendisplay of exemplary user interface 800, often displayed within thebrowser window 225 of FIG. 1, for presenting the search resultsorganized by task groups 270 along with various features that arederived from analyzing patterns of user search behavior. Further,exemplary user interface 800 FIG. 8 is rendered in accordance with anembodiment of the present invention, and is not meant to limit the scopeof representations that can express search results 290/instant answers259 organized by task groups 270.

Initially, a search entry area 820 is provided for accepting the query285. Upon entering the query 285, the corresponding task groups 270 areselected. Typically, at least a portion of the selected task groups 270are rendered at the exemplary user interface 800. In one instance, theselected task groups 270 are listed in a table of contents (TOC) 810placed in a strategic location on the exemplary user interface 800. Asshown, the TOC 810 is positioned as a right-rail panel. A set ofautomatically generated related searches 860 may be presented uponissuing the query 285. As shown, the related searches 860 are relevantto narrowing the query 285 and are published within the TOC 810.

The rendered task groups 270 may include those originally selected taskgroups 840 (e.g., based on analysis of the user search behavior 232 ofFIG. 2), as well as the instant answers 259 (e.g., generated by theinstant answers component 258 of FIG. 2). Further, a portion of thesearch results 830 organized by the task groups 270, which areresponsive to the query 285 in conjunction with the first of the taskgroups “Parts” 850, are listed below a heading that describes the firsttask group “Parts” 850. Further, another portion of the search results(not shown), which are responsive to a search using the second of thetask groups “Used,” may be located further down the exemplary userinterface 800 below a heading that describes the second task group“Used.” Accordingly, as shown, the organized search results 830 arearranged as a block on a webpage, or page element, specific to one ofthe task groups 270.

By grouping together the organized search results 830, the user isquickly directed to, and able to easily identify, the type of resultsthat are associated with one of the task groups 270. This concept may beapplied to navigational galleries (i.e., queries with navigationalintents) (e.g., Yahoo, Facebook, and the like), where the users intendto navigate directly to a particular site. That is, by grouping theresults related to the navigational galleries in a block under a headingreflecting a task group of “Navigational Gallery” (not shown), it iseasier for users to get to a particular site because the results are ina category unto themselves.

In embodiments, certain task groups of the listed task groups 270 may beassociated with a certain media type. For instance, the “Images” taskgroup may include search results that are digital images of the query285, as opposed to text. Similarly, the “Videos” task group may includesearch results that link to video files associated with the query 285.

As discussed above, each of the task groups 270 (e.g., “Parts,” “Used,”“Forum,” “Accessories,” etc.) each have a distinct set of search resultsassociated therewith and, typically, presented in proximity therewith.Often, a same number of the search results is presented with each of thetask groups 270, in order to provide the user with a consistent searchexperience. These blocks of search results will become visible as a userscrolls upward or downward on the exemplary user interface 800.

In embodiments, each of the task groups 270 are provided with aselectable link, where the link navigates to a separate UI that liststhose search results related to a particular task group. Accordingly, ifa user desires to view a comprehensive list of search results thatrelate to a specific task group, a selection (e.g., user-click action)may be applied to one of the task groups 270. This separate UI mayinclude some of the features presented on the exemplary user interface800 and remove others (e.g., the TOC 810).

As shown in the illustrated embodiment, a top-tanked document 840 of thesearch results may be granted a predominant position on the exemplaryuser interface 800. In an exemplary embodiment, the top-ranked document840 is a rich multimedia snippet of data. That is, the top-rankeddocument 840 may be a highest placed search result that includes aportion of text from a webpage and/or a digital image preview.

Turning now to FIG. 3, a flow diagram illustrating an overall method 300for automatically organizing search results according to task groups isshown, in accordance with an embodiment of the present invention.Although the terms “step” and/or “block” may be used herein to connotedifferent elements of methods employed, the terms should not beinterpreted as implying any particular order among or between varioussteps herein disclosed unless and except when the order of individualsteps is explicitly described.

Initially, a gallery of entities is aggregated into a query class, asdepicted at block 310. As defined above, the “gallery of entities”generally corresponds to queries that share a common categorization. Asdepicted at block 320, a dictionary is assigned to the query class. Alsodefined above, the “dictionary” comprises a list of terms that are drawnfrom one or more sources (e.g., retrieved from the data stores 230 ofFIG. 2). The task groups are identified from the list of terms withinthe dictionary, as depicted at block 330. In an exemplary embodiment,the process for identifying the task groups includes, at least, thesteps of analyzing patterns of user search behavior to select one ormore terms from the list of terms that reflect popular user searchintents (see block 340), and ranking the selected terms based onpredetermined parameters (e.g., frequency of use in a query, number ofentities that correspond to terms, and the like) the to produce anordering. As depicted at block 360, a set of the terms, which arehighest ranked based on the ordering, are considered to be the taskgroups. As depicted at block 370, the task groups are persisted, atleast temporarily, in association with the query class.

With reference to FIG. 4, a flow diagram illustrating an overall method400 for collapsing a list of terms within a dictionary by analyzingcomponents of a query is shown, in accordance with an embodiment of thepresent invention. Initially, a query log is accessed, as depicted atblock 410. Typically, the query log includes a plurality ofuser-initiated queries corresponding to the entities designated as partof the query class. As depicted at block 420, components of each of theplurality of user-initiated queries are analyzed to identify one or moreterms of the dictionary that map to at least one of the entities. Also,the plurality of user-initiated queries are analyzed to identifymodifiers of the one or more terms. Typically, the modifiers includeprefixes, which precede the terms that are identified as mapping to theentities in the query class, or suffixes, which follow the terms thatare identified as mapping to the entities in the query class. Further,in embodiments, the modifiers correspond to terms in the dictionaryassigned to the query class.

As depicted at block 430, a set of the modifiers that most frequentlyoccur as a component within the plurality of user-initiated queries iscompiled. In addition, as depicted at block 440, amost-frequently-occurring set of modifiers is established as the taskgroups. The modifiers (prefixes and the suffixes) that are commonlyemployed to refine a search with a particular entity from the gallery ofentities are identified, as depicted at block 450. These identifiedmodifiers are associating with each other, as depicted at block 460. Asdepicted at block 470, the list of terms in the dictionary is collapsedby moving the associated modifiers to a single entry within thedictionary.

Referring now to FIG. 5, a flow diagram illustrating an overall method500 for utilizing a user's reactions during a search to identify termsin the dictionary as task groups is shown, in accordance with anembodiment of the present invention. Initially, as depicted at block510, a related-searches list is accessed. As defined herein, the“related-searches list” typically includes terms from the dictionarythat are offered to users while conducting a search. In embodiments, thesearch is conducted by entering a query that includes as a component anentity from the gallery of entities. Eventually, a session analysis ispreformed utilizing the related-searches list. In one instance, thesession analysis includes compiling historical reactions of the userswhen selecting the terms in the related-searches list when refining asearch (see block 520) and identifying a set of the terms in therelated-searches list that have most-frequently received a positivereaction from the users (see block 530).

Examples of the positive reaction provided by the users include aclick-through on a term from the related-searches list and a selectionon a follow-on webpage rendered in response to the click-through. Asdepicted at block 540, the identified set of terms are established andstored as the task groups.

Turning now to FIG. 6, a flow diagram illustrating an overall method 600for manipulating a composition of a list of terms associated with aquery class is shown, in accordance with an embodiment of the presentinvention. In embodiments, a gallery of entities is compiled to form thequery class, as depicted at block 610. Typically, each entity in thegallery of entities corresponds to a query that shares a commoncategorization (e.g., musicians, cars, cities, and the like) with otherqueries that are represented by other entities in the gallery ofentities. As depicted at block 620, a list of terms is extracted from atleast one data store. In one instance, each term in the list of terms isassociated with a search refinement path of the query. Typically, thequery includes one or more entities compiled in the gallery of entities.A structured searchable database is scanned to identify equivalencesbetween terms within the list of terms, as depicted at block 630.

In an exemplary embodiment, scanning the searchable database to identifyequivalences between terms within the list of terms involves performinga process that includes the step of mining the structured searchabledatabase for redirects that indicate synonymous terms, as depicted atblock 631. As depicted at block 621, a determination whether thesynonymous terms appear in the list of terms is performed. If thesynonymous terms do appear in the list of terms, the composition of thelist of terms is condensed by removing one or more of the synonymousterms, as depicted at block 633.

Returning to the overall method 600 for manipulating a composition of alist of terms, the structured searchable database is scanned to identifyrelevant terms that share a common categorization with the query class,as depicted at block 640. In an exemplary embodiment, scanning thesearchable database to identify relevant terms that share a commoncategorization with the query class involves performing a process thatincludes the step of mining the structured searchable database fortopics that categorize the gallery of entities assembled to form thequery class, as depicted at block 641. As depicted at block 642, a scoreassociated with one or more of the topics is incremented upondetermining an entity, of the gallery of entities, is categorizedthereby. The scores, which are associated with each of the topics, arethen compared against each other to distill a set of highest scoringtopics from the topics, as depicted at block 643. As depicted at block644, the composition of the list of terms is expanded by incorporatingterms categorized by the highest scoring topics into the list of terms.

Again returning to the overall method 600 for manipulating a compositionof a list of terms, the composition of the list of terms is condensed orexpanded by applying the equivalences or the relevant terms,respectively, to update the list of terms, as depicted at block 650. Thelist of terms is then replaced with the updated list of terms, asdepicted at block 660. As depicted at block 670, the updated list ofterms, in association with the query class, is written to a storagelocation on computer-readable media.

With reference to FIG. 7, a flow diagram illustrating an overall method700 for utilizing task groups to automatically organize search resultson a UI display is shown, in accordance with an embodiment of thepresent invention. Initially, the overall method 700 includes the stepof providing a plurality of dictionaries, as depicted at block 710.Typically, each of the plurality of dictionaries includes a list ofterms. In an exemplary embodiment, each term in the list of terms, atsome point, helped refine a search for an entity within a gallery ofentities. As discussed above, each entity in the gallery share a commontheme with the other entities. As depicted at block 720, one or moreterms, from the list of terms, are identified as reflecting popular usersearch intents of users. Typically, a predefined timeframe is employedfor identifying the terms that reflect popular search intents of users.As depicted at block 730, one or more identified terms is promote to thetask groups.

Eventually, a user-issued query comprised of search terms may bereceived, as depicted at block 740. In one instance, the search termsmap to an entity associated with one or more of the plurality ofdictionaries. Incident to receiving the user-issued query, a dictionaryis selected from the plurality of dictionaries, as indicated at block750. As indicated at block 760, the task groups associated with theselected dictionary are recognized. Search results that are responsiveto the query in conjunction with each of the recognized task groups areretrieved, as depicted at block 770. As depicted at block 780, apresentation device is instructed to render on a UI display those searchresults in a format that is organized by the task groups. In oneinstance, the format includes blocks of search results that are locatedproximate to, and correspond with, each of the task groups,respectively.
